Specification forming part of Letters Patent No. 133,274, dated November 19, 1872.

erence being had to the accompanying draw-.

ing and to theletters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a device for rounding leather or other material, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the samefI will now proceed to describe its construction and operation, referring to the annexed drawing, in which-,

Figure l is a perspective view from the under side showing my device closed. Fig. 2 is a similar view from the top, showing my device partially open and Fig. 3 is a cross-section through Fig. 1.

A A represent two side bars placed in an inclined position toward each other, their front ends being closer together than their rear ends, and the former connected by a crossbar, B.

The rear ends of the'side bars A A form the outer parts of a hinge, the center part of which is formed by the rear end of a bar, (2, which is shaped so as to fit between the side bars A A, and when closed held by one or more buttons, D, as shown in Fig. 1. Theinner edges of the side bars A A, as well as of the cross-bar B, are beveled inward from the upper side downward, and the edges of the center bar 0 are beveled in theopposite direction,

so as to fit properly in its place. In the joint on both sides and end of the center bar 0 are made holes a, a, of substantially the shape shown in Fig; 3, through which to pass the leather or other material to be rounded. These holes are of various sizes, so as to accommodate articles of different thickness, the joints or beveled edges of the bars running diagonally across said holes. My rounder thus opens on an angle which forms each jaw about threefourths of the way around the article to be rounded, so that when the rounder is closed Letters Patent, is
